Asset Attribution Surface Contract

Large Theory

Asset license records answer whether we know the source. Attribution surface contracts answer whether users and delivered artifacts can also see that source. CC BY, map tiles, photography, illustrations, music, Lottie, open patterns, and custom-licensed assets often require credit, license links, and change notes. Agents should not hide attribution only in JSON, EXIF, or alt text; they must decide where credit appears, how it avoids task friction, whether it survives export, and whether it avoids implied endorsement.

Small Points

1. CC attribution is organized around TASL: Title, Author, Source, and License; 4.0 also expects reasonable change notes and license links.
2. Placement depends on medium: next to the image, footer, credits modal, resource detail, exported PDF/slide footer, or end credits. It cannot live only in backend metadata.
3. Alt text explains image meaning; it is not the place to pack license statements. Use visible credit or source notes for licensing.
4. Multiple-source assets need one-to-one attribution, not vague copy such as Creative Commons images or icons from the internet.
5. Cropping, recoloring, translation, compositing, and generative edits need change notes; ND or no-derivatives terms should block adaptation paths.
6. Commercial-use risk, attribution requirements, and no-endorsement limits should appear with download or copy actions so agents do not silently use the asset in client work.

Design Judgment

Attribution is healthy when users can find author, source, license, and modification notes from the page or exported artifact that uses the asset, without implying that the author or brand endorses the product. If credit appears only in a database, alt text, file name, or internal PR, the rights chain is still broken.

Implementation Notes

Generate an attribution surface record for every attribution-required resource: assetId, title, author, sourceHref, licenseName, licenseHref, modificationNote, creditPlacement, exportPlacement, visibleLabel, machineMetadata, commercialUse, noEndorsementNote, and reviewDate. UI may use a compact credits list, media caption, details drawer, or footer credits. PPT/PDF/image export should include a credits slide or side note.

Counterexamples/Risks

Putting CC BY image author names into alt text and creating screen-reader noise, storing the license only in the asset catalog with no public credit, losing credits during PDF export, cropping an image without noting the modification, embedding CC BY work in a paid template without a route to the original license, and using customer logos in a way that implies partnership.

Case Study

Creative Commons recommends Title, Author, Source, and License in attribution and explains that the exact surface can be reasonable to the medium. The CC BY 4.0 deed requires appropriate credit, a license link, change indication, and no implied licensor endorsement. W3C image guidance separates informative and decorative images and shows that decorative images can have empty alt text, which means alt is an accessibility meaning channel rather than a license-credit container. The reusable lesson is that attribution, accessible text, and layout each need their own role.
